Whistle, click the bot. Then, click the name (left part of the name) and keep the mouse over the name while typing the new name.
Press return and you are there :)
Doesn't works for me :'(
Now you need to make a Wooden Badge, put it into the Bot's upgrades, then you can click the name to rename it. Thanks!
this works perfectly ! Thx a lot Denki.
Thanks for the badge this helps a lot with organizing their jobs
